Philips 34" InstantFit 4000K cool white glass 11 watt dimmable T5 LED lamps are compatible with most instant-start ballasts. They eliminate the need to have an electrician rewire the fixture. Simply take out the existing fluorescent T5 lamp and replace with the Philips LED T5 InstantFit lamp. They are an ideal energy saving choice for existing linear fluorescent fixtures. Suitable for use in fixtures where ambient temperature is between -4°F and 113°F. Can be used in lensed recessed troffers.

Compatible with most instant-start ballasts. Does not work with magnetic or rapid-start ballasts. Power to fixture must be turned off before replacing the lamp. Call one of our Lighting Specialists at 888.455.2800 for details.

Fluorescent Equivalent

The total wattage of fluorescent lamps in a fixture that this fixture replaces.

Volts

A measure of "electrical pressure" between two points. The voltage specification of an incandescent lamp is the electrical "pressure" required to drive it at its designed point. The "voltage" of a ballast (e.g. 120 V) refers to the line voltage coming from the power source and is connected to the ballast.

Volts

50-80

Base

The end (or ends) of the lamp that fits into the socket.

Bulb Shape

The description of the general appearance of a lamp/bulb consists of a letter(s) followed by a number. The letter indicates the shape of the bulb and the number relates to the diameter of the bulb in eighths of an inch. For example, a common household bulb is the A-19. The bulb is "A" shape and the diameter would be nineteen 8ths of an inch, or 2 3/8".

Bulb Color

The color of the light produced by a bulb

CRI

Color Rendering Index is an international system used to rate a lamp's ability to render object colors. The higher the CRI (based upon a 0-100 scale) the richer and more accurately colors generally appear. CRI differences among lamps are not usually visible to the eye unless the difference is more than 3-5 points.

CRI

82

Color Temperature (Kelvin)

An expression of the hue of the light emitted, measured in degrees Kelvin. Usually expressed by a four digit number followed by (k), such as 2700k. Higher temperatures indicate whiter, "cooler" colors, while lower temperatures indicate yellower, "warmer" colors. Some common Kelvin temperature benchmarks are 2700k (warm white), 3500k (neutral white), 4100k (cool white), 5000k (bright white), and 6500k (daylight).

Brightness (Lumens)

A rating of the initial light output of a bulb, rated after 100 hrs of operation. Lumens are a measure of how much light falls on one square foot of area, one foot away from the light source.

Average Rated Life (hr)

A measurement of the average length of time, between first use and the point when 50% of the lamps tested have stopped functioning, , using an operating cycle of 3 hours on, 20 minutes off.

Operating Temperature (°F)

The ambient temperature in which the product can safely operate.

Beam Angle (°)

The width of a light beam, expressed in degrees. The beam angle is often part of the ordering code for reflector lamps. For example, a 50PAR30/HIR/NFL25 is a 50-watt PAR30 narrow flood lamp with a beam angle of 25 degrees.

Length (in)

Also referred to as "Maximum Overall Length" (MOL). For light bulbs, it measures the length of a light bulb, from the top of the bulb to the bottom of the base or pins and is typically expressed in inches. For light fixtures and ballasts, it applies to the total horizontal length of the item.

Dimmable

Indicates whether a bulb can be dimmed in conjunction with a suitable dimmer control.

Rated for Fully Enclosed Fixtures

Not all LED bulbs are suitable for use in enclosed fixtures, due to the amount of heat they generate. Rated bulbs have been tested and approved as safe for enclosed fixtures.
